The majority of commercially-available polypropylene sleeves are 1 to 1 5 mil Our polyethylene sleeves are 2 mil and 3 mil respectively In more chemistry-speak propylene (CH3CH:CH2) is is a sub-stratum of ethylene Ethylene is the purest form of the base chemical and thus the purer better of the two
To make woven polypropylene plastic threads are woven together in a more traditional manufacturing process to create a durable material To create non woven polypropylene plastic fibers are bonded together In both instances the fabric is durable and when used to make reusable bags they will deliver years of dependable use
